摘要
以水分子(H2O)双振子二次量子化哈密顿量作为理论模型,通过加横向扰动研究H2O中氢氧(O—H)耦合量子态的稳定性。结果表明:当水分子中的两个振子能量集中于其中之一时,不易受横向扰动的影响,稳定性好;当振子能量不对称时,极易受横向扰动的影响,稳定性迅速衰减、变差;当两振子振动强度一致时,不易受弱横向扰动的影响,对于比较强的横向扰动稳定性演化曲线呈现近周期性变化,说明该状态在强扰动下极易发生可逆性的跃迁。
Abstract
In this paper, based on the theoretical model of the second quantization Hamiltonian of a water molecules (H2O) with double oscillator,we study the stability of hydrogen and oxygen (O-H) key oscillator in a H2O by adding lateral disturbance. The results show that when the energy of the two vibrators in the water molecules are concentrated in one of them, it is not easy to be affected by lateral disturbance.When the vibration energy is asymmetrical, it is easy to be affected by lateral perturbation.i.e., the former does better then than the latter in stability.When the vibrational strength of the two oscillators is consistent, it is not easy to be affected by the weak lateral disturbance, but the Strong disturbance causes periodic changes of the stable evolution curve. It is indicated that this state can be easily reversibility under a strong disturbance. It is also stable on the time average.
